Kimberley Moulten, an adjunct curator at  Britain's Tate gallery, specialising in First Nations art and Kate ten Buuren, a Taungurung curator, walk us through the public installation Blak Infinite for Melbourne's winter arts festival, RISING.

The artist Destiny Deacon, who passed away last week, first coined 'Blak' to reclaim a word often weaponised against Aboriginal people in Australia. Rosa speaks with the Art Show's own Daniel Browning, who knew Destiny, about the artist's influential work and daring humour. Work mentioned include Whitey's Watching  and Eva Johnson -- Portrait .

In the 1930s Grace Crowley taught at a private painting school and met Ralph Balson, a house painter. The two struck up a lifelong painting practice that moved into 'pure abstraction', together playing an important role in the art movement in Australia. We look at their work and still-undefined relationship with curator Beckett Rozentals, for a new exhibition placing them side by side.
